    Architects must react to the land available without predicting its realistic development capacity. They have had no way of efficiently forecasting capacity without time-consuming drawings that explore a limited number of options, and no way to insist on minimum levels of project open space to offset building mass and pavement that produce intensity.

     

    Open space, however, determines the weave of urban fabric and form, and we have little knowledge about the impact of fabric, form and intensity on our daily quality of life. This, however, determines the relationship between architecture and public benefit beyond the box. It also determines the relationship of the Natural Domain to the sustainable future of an artificial environment called the Built Domain. In other words, open space is critical, but architects cannot predict its impact on development capacity at the project level, let alone argue for city design plans that emphasize the integration of architecture with the Natural Domain.

     

    This is organic architecture and city design, but it cannot proceed without the tools needed to predict the relationship between development capacity and open space at the project level, since this is where real estate value is calculated. Conscious project open space provisions have been ignored because their limits on development capacity could not be efficiently predicted. Project open space has been a left-over. Inclusion has been arbitrary and mandatory requirements have been considered a "taking" of individual property rights. A new method of measurement and calculation, however, offers a new ability to accurately and efficiently predict the development capacity implications of open space provisions, and to ensure equal treatment on the basis of improved knowledge.  Project open space is the missing design decision and it must align with our need to shelter growing populations within a sustainable Built Domain that retains its quality of life. This is the promise of organic architecture and city design. There's a lot to learn because we have not been able to define and measure intensity, let alone study its implications.

     

    Intensity begins with architecture in the Shelter Division of the Built Domain. The Built Domain remains to be defined, but the built environment continues to expand its consumption of the Natural Domain. Shelter is served by the Movement, Open Space (agriculture, public open space) and Life Support Divisions of the built environment. This environment will continue to threaten the Natural Domain until organic architecture and city design live up to the promise implied by Louis Sullivan and Frank Lloyd Wright. This will not happen until improved measurement systems can support organic research. We are currently borrowing engineering measurements to define energy conservation and consumption while consuming the land with abandon. This is not organic design. It is sprawl.

     

    Intensity measurement can become the foundation for organic urban research. It will eventually become essential, because development capacity must equal population growth within a limited Built Domain. Intensity measurement, evaluation and prediction is the future public benefit of architecture, and one reason why I began work on the second version of Development Capacity Evaluation software. It is attached to the second edition of my book, Land Development Calculations published by The McGraw-Hill Companies in 2010. This sounds like a blatant attempt to sell software explained by a book, but it represents my sincere desire to make a contribution.

     

    It's time that city fabric and form represent the goal of organic function within an urban biological system that can achieve symbiotic status with its natural partner. This can only begin with a measurement system equal to the research, evaluation and knowledge required to improve design decisions by individual practitioners. It cannot be achieved without consciously addressing a missing design decision that offsets intensity and is the foundation for our quality of life. There is no question in my mind that architecture will be recognized as a public benefit when it leads, or joins, a collaborative professional and scientific effort to study the implications of design specifications and their ability to take organic design to the next level of cultural adaptation. At this point, design specification knowledge will be supported by local, state and national governments.

     

    AUTHOR NOTE: The problem has been that we have not been able to accurately predict the development capacity of land when a specified amount of project open space is retained as a contribution to both project and urban context. This makes intensity a wild card that is dealt by chance from a land owner's deck and sprawl an inevitable result. When an architect leaves project open space to chance however, he isolates himself and is less able to convince others of public benefit. This is why I have focused on the ability to predict development capacity options (intensity options) when project open space is specified. Forecast models make it possible to predict hundreds of these options in a fraction of the time it would take to sketch one. It can change the way we appraise, use and preserve the land for future generations, and is one step closer to the dream begun by Louis Sullivan, Frank Lloyd Wright and Rudolf Frankel.-------------------------------------------

    That sounds a little similar to the approach I take on some of these issues, asking not how much information do I have, but if there's a way to tell how much information I'm missing.   That way of changing the question itself reorients your inquiry away from your own theory to treating your environment as the wilderness it actually is, that new relationships need to be built to get along with.   

    For example, when people have been adding up the energy use their projects are responsible what you have information about is found in the form of receipts paid to energy companies, and you collect them from the business and the supply chain as far as you can go as the standard way to estimate the total.   

    If you ask what energy use information you're missing it's a whole different picture.  Then you begin to count the energy uses outsourced by purchasing all the many kinds of services businesses use, that are not direct energy using technology.   My estimate was that when you do a good job of combining both, for a wind farm in the example, the total energy use and CO2 footprint for generating of wind energy goes up ~500%...  just for asking the environmental question the right way.

    Most cities require some degree of open space based on location and use. The City of Scottsdale requires natural open space (NAOS) as part of it's environmental sensitive lands ordinance (ESLO) in over half of the city - http://www.scottsdaleaz.gov/codes/eslo

    The are not many projects that have successfully integrated urban density with interconnected public and private open vegetated spaces on a three dimensional scale. After designing and building a number of mid-rise condo projects (Chicago and Phoenix) and completing several custom homes in Scottsdale under the ESLO, Optima Development (David Hovey, architect/developer) recently completed a mutl-family mixed use project (50 units per acre) in downtown Scottsdale that seeks to integrate the natural and built domains in an urban setting. The project consists of 11 interconnected terraced buildings (5-6 stories) on a 13 acre infill site. It is a groundbreaking project for the southwest and perhaps a new prototype for integrated urban architecture.
